V Application tiled September 3, 1904. Serial No. 223,267.

Be it known that l, HENRY D. ritorna, a citizen ot the United States ofAmerica, residing at Sharpsburg. in the county ol Allegheny and tritateot' Pennsylvania, have invented certain new and useful Improvements inWrrenches, el which the following is a specification, ret erence being'had therein to the accompanying' drawings.

'lhis invention has relation to certain new and useful improvements inwrenches, and more particularly to that type commonly known as"spanner-wrenches, which are employed for removing nuts from thespindles ot axles and the like; and the object oiI this invention is toprovide a novel form of wrench which may be quickly adjusted to the nutand retained thereon until the nut is removed and the wrench disengagedfrom the nut.

Referring to the drawings accompanying this application, like numeralsoi' reference in dicate similar parts throughout the several views, inwhich Figure 1 is a perspective View of my improved wrench, showing thesame applied toa nut which is to be removed trom the end of an axle orspindle. Fig. 2 is an end view ot the wrench. Fig. 3 is a view ol. theopposite end or handle portion of the wrench.

To illustrate the use of my improved wrench, l have shown the end of aspindle as designated by the reference-numeral 1, this end oit' thespindle carrying' a nut 2, which is shown in dotted lines in Fig. 1 otthe drawings. The wrench as preferably constructed consists ot' twosemicylindricalshells 3 and 4L, these shells having' their sides cutaway, as designated at 5, to reduce the weight oiI the same. 1n formingthe semicylindrical shells 3 and 4 I retain at their ends the material(5 and 7 and iorm this material so that the shell 4c will be providedwith i'langes V8 and the shell 3 will be provided with depending flangesQ, which will engage the iianges 8 ot' the lowerf shell and hold saidshells together. To Yform the lianges 8 and 9, the material 6 and 7,retained in the ends ot' said shells, is drilled, as desig-l nated at 10in the shell 3 and as at l1 11 in the shell li, this construction being'clearlyv shown in VFig. 3 of the d rawings. The periphu ery ot' eachshell is constructed with diametrically opposite pins 12 12, whereby ametallic ring' 14, which is carried upon the periph ery ot' said shells,is retained thereon and prevented 't'rom becoming' detached 'from theshell except when they are separated from one another, which isaccomplished by placing' the metallic ring 1e upon the ond ot' thewrench and by sliding one shell without the other, as will bepermissible by the construction shown in lFig. 3 of the drawings.Centrally ot' said tongs is provided the reinforcing-strip 15, which isformed integral witheach shell, and the innel' sides ot' the shells 3and el: opposite these reinforcing-strips are provided with col lars 16and 17, and the collar 16 oli' the shell 3 is provided with ascrew-threzuled aperture through which a screw-bolt 18 passes. Thisscrew-bolt normally bears in the collar 17, and the screw-bolt isemployed to adjust the shells 3 and ft for diii'erent-sized nuts whichare to be gripped by said wrench.

In :forming the outer end of the wrench, which is adapted to grip thenut, l. retain a portion ot' the material, as designated by thereference-numerals 119 19, and form the material of each of the shells 3and 4f with angular sides 20 and 2l, whereby the face of a nut may bereadily gripped by the wrench.

The shells 3 and Li comprising the wrench are formed with countersunksurfaces 22 22, and in these surlaces i form annular recesses 23 23 toreceive a suitable lever it'or rotating the wrench in either direction.

1n practice the ring 14 is moved rearwardly until it engages the pins 1212, at which time the shells 3 and 4L of the wrench may be opened tosuchI an extent as will be permitted by the metallic ring 14 and theconnected ends oi the shell. The wrench is then closed to embrace thenut in its jaws .19 19 and the ring slid forward on the cut-away edgesto clamp the jaws in the said position. 1V hen the wrench is closed onthe nut, any suitable lever is brought into play to rotate the wrench,the said lever beingl inserted in apertures 23 23. The screwbolt may beadjusted when it is desired to grip nuts other than that shown in theaccompanying' drawings.

It will be noted that various changes may ICJO be made in the details ofconstruction, such as the shape and size ot' the wrench, withoutdeparting from the spirit and scope of the invention.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

l. A wrench comprising two sections having their corresponding endsdetachably locked together by interlocking means formed integral withthe sections, the edges of said sections having cut-away portions, andmeans arranged on said portions for holding said sections together.

2. A wrench comprising two semicylindrical sections having their edgespartially cut away, a securing means on said sections adjacent saidcut-away edges, and integral interlocking langes on the edges fordetachably locking the sections together.

3. A wrench comprising two semicylindrical sections havingcnt-awayedges, a ring arranged thereon and having' its rearward movementarrested by pins on said sections, the rear ends ot' said sections beingremovably locked together, and the forward ends formed with jaw-faces,an adjusting-screw on one ot' said sections for engagement with theopposing section, and said wrench being formed with suitable means to beengaged by any suitable lever for rotating the wrench.

4. A wrench comprising two sections` the rear ends thereof being formedwith flanges, the iianges of one section being flared to interlock withthe iianges of the other section.

5. A wrench comprising two sections having flanges forming a fulcrurntherefor, the ianges of one section projecting inwardly to embrace theflanges of the opposing section.

6. A wrench comprising' two sections,flanges on the rear end thereof,interlocking eXtensions on said flanges, the extensions on one sectionprojecting inwardly and those on the other section projecting outwardly.

In testimony whereot` I aiiiX my signature in the presence of twowitnesses.
